Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989662, here are decompositions:

83 + 989579 = 989662
101 + 989561 = 989662
239 + 989423 = 989662
251 + 989411 = 989662
281 + 989381 = 989662
353 + 989309 = 989662
383 + 989279 = 989662
431 + 989231 = 989662

Showing the first eight; more decompositions exist.
